New golf, same problem

Its unlikely to be the alternator itself, it'll be just the voltage regulator thats attached to it.

If you take it to a specialist they'll sort it out for around ?15 or so (usually) not sure if you can buy the regulators themselves or not.

I used some 2x6mm wire from the alternator to the battery to improve charging,  worked a treat.

Ive actually got a spare voltage regulator but I fear its probably as bad as the one thats in. I think they,re only cheap from gsf.

I think I'l try another live from the alternator, certainly cant hurt eh?

Thanks for that bud,I'l let you know if it works…sorry for hijacking. ops:

just incase anyone finds this through the search engine just like to say i've resolved the problem and it was a knackered belt so it was slipping on the alternator and not giving out enough power.
